phpBB 3.0 RC4

We are very pleased to announce the availability of the phpBB3 RC4 package - the
"Celebrate the unknown Birthday" Edition. This is the fourth release
candidate which is meant to become the Gold release if no more bugs or problems
arise.

For release candidates full support is given, allowing language packs as well as
modifications and styles. We only give support to those having a clean RC
installation or updates from previous release candidates, previous conversions
or updates from betas will not be supported here. We encourage only those
running the release candidates wanting to test out the new version, it is still
recommended to wait for the full release; after all this is a release candidate.

Please also note that we urge you to update - we only support the latest
version. Bug reports submitted for previous releases will be closed as well as
only the latest version being supported here.

RC4 has seen quite a lot of improvements, the software should be overall much
more stable. Some important fixes are for example:

[Feature] Let the user choose how to update modified files (merging, using
new file or using old file) within automatic updater

[Feature] Allow "older" updates applied with the automatic
updater. This allows people using it for updating, say, from 3.0.0 to 3.0.1
(with the correct package of course) and then from 3.0.1 to 3.0.2 if the
latest version at this time is 3.0.2. These changes take effect beginning
with RC4 or people replacing install/install_update.php manually prior doing
the updates.

[Feature] Ability to disable birthdays completely with new board features
setting

[Feature] Ability to externally set $phpbb_root_path if wrapping phpBB3 by
defining constant PHPBB_ROOT_PATH

[Change] Add version number to ACP index (Bug #13703)

[Change] Improved utf8_clean_string with a more complete list of
homographs and NFKC normalization

[Change] Re-implemented All Yes/No/Never links in permission panels for
easier changing all categories at once

[Change] Advanced permission link now "marked" if no role is
assigned and custom permissions set. With this an admin can instantly see if
the object is not set at all or having custom permissions, something you
only saw if advanced permissions were viewed before.
